Erasca, Inc. (ERAS) filed an SEC Form 8-K — Results of Operations and Financial Condition. Exhibit 99.1 Erasca Reports Second Quarter 2026 Business Updates and Financial Results Updated ERAS-0015 data in U.S. trial highlighted compelling monotherapy efficacy in 2L+ KRAS G12X PDAC and continued favorable tolerability, as well as further advancement of panitumumab CRC co
How this was made
The 30-second read
Why it matters
Traders can update ERAS’s probability-weighted pipeline outlook based on new efficacy and safety datapoints, and reassess funding needs after the upsized July public offering.
Market read
Fresh clinical efficacy and safety detail plus quantified cash and an upsized financing can shift near-term biotech risk pricing and catalyst expectations.
What to watch
R&D expense increased sharply year over year, and the cash runway is tied to upcoming milestones that may slip; combination backfill and dose escalation timelines could affect near-term data cadence.
Erasca Reports Second Quarter 2026 Business Updates and Financial Results
The quarter combined updated preliminary ERAS-0015 clinical data, defined upcoming pipeline milestones, and a strengthened cash position following financings, although operating expenses and net loss increased from the prior-year quarter.

What drove it
- At the recommended dose for expansion of 32 mg once daily, ERAS-0015 demonstrated a 57% uORR 8wk in 2L+ KRAS G12X PDAC, with ongoing treatment across all responding patients and most enrolled patients.
- ERAS-0015 reported mostly low-grade treatment-related adverse events, no dose-limiting toxicities, no treatment-related discontinuations, and a median relative dose intensity of 100% at both the 24 mg QD and 32 mg QD RDEs.
- The company cleared the first 16 mg dose-escalation cohort of ERAS-0015 in combination with panitumumab after demonstrating no DLTs; backfill enrollment is ongoing in the 16 mg combination cohort and dose escalation is continuing in the 24 mg combination cohort.
- R&D expense increased primarily due to clinical trials, preclinical studies, discovery activities, outsourced services, consulting fees, and personnel costs, including stock-based compensation expense.
- G&A expense increased primarily due to personnel costs, including stock-based compensation expense, and legal costs.
Concerns
- Net loss was $44.1 million for the quarter ended June 30, 2026, compared to $33.9 million for the quarter ended June 30, 2025.
- R&D expenses were $35.9 million for the quarter ended June 30, 2026, compared to $21.2 million for the quarter ended June 30, 2025.
- The company stated that interim, topline and preliminary clinical-trial results are not necessarily indicative of final results and may materially change as enrollment and follow-up continue.
- Potentially registration-enabling trials may be delayed based on FDA feedback or requirements, and successful planned trials may not support regulatory approval.
What to watch
- ERAS-4001 preliminary Phase 1 monotherapy data expected in the second half of 2026.
- ERAS-0015 Phase 1 monotherapy expansion data expected in the first half of 2027.
- ERAS-0015 Phase 1 combination dose escalation data, including the panitumumab combination, expected in the first half of 2027.
- Potential initiation of the ERAS-0015 2L+ NSCLC potentially registration-enabling trial in the first half of 2027.
- Phase 3 pivotal trial initiation plans for 1L PDAC in 2027 and RASm NSCLC in the second half of 2027 to the first half of 2028.
- Use of the July 2026 underwritten-offering net proceeds and the company's stated ability to fund the listed upcoming milestones.
Balance sheet and cash flow
- Cash, cash equivalents, and marketable securities were $384.3 million as of June 30, 2026, compared to $341.8 million as of December 31, 2025.
- In July 2026, Erasca completed an upsized public offering, raising approximately $632.5 million in gross proceeds.
- Erasca's January 2026 upsized public offering raised approximately $258.8 million in gross proceeds.
Analysis
Erasca's second-quarter update centered on clinical progress rather than commercial performance. ERAS-0015 produced a 57% uORR 8wk at the 32 mg once-daily recommended dose for expansion in 2L+ KRAS G12X PDAC. The company also reported ongoing treatment across all responding patients and most enrolled patients, alongside mostly low-grade treatment-related adverse events, no dose-limiting toxicities, no treatment-related discontinuations, and a median relative dose intensity of 100% at the 24 mg QD and 32 mg QD RDEs.
The development plan broadened during July. The company cleared the first 16 mg ERAS-0015 plus panitumumab dose-escalation cohort with no DLTs, is enrolling a backfill cohort at that dose, and is continuing escalation in the 24 mg combination cohort. Management identified ERAS-0015 monotherapy and combination data in the first half of 2027 as key next disclosures, while ERAS-4001 preliminary Phase 1 monotherapy data are expected in the second half of 2026.
Expenses and loss increased from the comparable prior-year period. R&D expenses were $35.9 million versus $21.2 million, driven by clinical trials, preclinical studies, discovery activities, outsourced services, consulting fees, and personnel costs. G&A expenses were $11.7 million versus $9.5 million. Net loss was $44.1 million, or $(0.14) per basic and diluted share, compared with $33.9 million, or $(0.12) per basic and diluted share. The release does not provide prior-quarter operating results, so quarter-over-quarter changes cannot be assessed from the filing.
Liquidity strengthened through financing activity. Cash, cash equivalents, and marketable securities were $384.3 million as of June 30, 2026, compared with $341.8 million as of December 31, 2025. Erasca subsequently completed an upsized public offering in July that raised approximately $632.5 million in gross proceeds, following an approximately $258.8 million gross-proceeds offering in January. The company stated that current cash, cash equivalents, and marketable securities, inclusive of net July offering proceeds, will be sufficient to fund the listed upcoming milestones.
The central execution issues are conversion of preliminary ERAS-0015 activity into subsequent data sets and progress toward the planned potentially registration-enabling programs in NSCLC, PDAC, and RASm NSCLC. The company explicitly notes that preliminary results may change with additional enrollment and follow-up, and that FDA feedback or requirements could delay planned potentially registration-enabling trials or require additional data.
Management, verbatim
Updated clinical data from our U.S. trial further bolster our excitement for advancing ERAS-0015, with compelling monotherapy activity in 2L+ KRAS G12X pancreatic cancer, previously disclosed encouraging data in 2L+ KRAS G12X lung cancer, sustained tolerability with longer follow-up, and promising combination potential.

Background
This SEC 8-K (Item 2.02) reports Q2 2026 business updates and financial results, alongside updated U.S. AURORAS-1 Phase 1 data for ERAS-0015 and plans to accelerate registration-enabling development.
Ticker impact
Erasca reported updated AURORAS-1 U.S. trial data for ERAS-0015, including 57% uORR at 8 weeks in 2L+ KRAS G12X PDAC and no DLTs.
Likely positive bias for ERAS shares as traders price in improved probability of registration-enabling progress and increased runway.
The filing is a primary disclosure with specific trial outcomes (uORR, tolerability, DLTs) and quantified cash/financing, which can move biotech risk perception and funding expectations.
Market effects
Reinforces investor appetite for early-stage precision oncology programs with pan-RAS strategies and combination expansion plans.
Primarily impacts U.S. small-cap biotech sentiment and Nasdaq clinical-stage risk appetite.
Limited direct global read-through, but may influence broader RAS-targeted oncology valuation narratives.
Counterpoint
uORR and early-phase tolerability do not guarantee durable responses or Phase 3 success; dilution risk remains if enrollment and trial costs rise.
